I'm using your iTunes cleaner and it keeps telling me that I have unwritable songs that need to be fixed.  I run refix and get same message at end of refix.  what does "unwritable songs" mean and how do I fix it?

it seems a register code is needed to try your system or to have it work or perform its actions. can i get a code to try it for 30 days.
Or do u need to purchase the tunes cleaner b4 u can use it,  if I need to do the purchase if I purchase do I have 30 days to try your system & if I do not like it would I receive a full refund  in the 30 days if I am not happy. thanks

Need updater for Mac Tunes Cleaner. Catalina will not launch to update within app.

I tried out the iTune Clearer thinking it would be an awesome tool but it flags all songs that have the artwork from iTunes as missing - not exactly useful. Almost always, the artwork from iTunes is superior and just because it's not embedded within the audio file is it missing - it will strill transfer to Apple devices.

Mac OS won't let me launch the app to update. I need to get an updater.

I tried using imElfin Tunes Cleaner on my Mac that runs MoJave, it is telling me I need an updated program that runs 64 bit not 32,
Is this correct?
Is there a 64 bit version?
